Innovations in red blood cell preservation

Area of Science:

• Transfusion Medicine
• Hematology
• Biopreservation

Background:

• Current red cell concentrate (RCC) storage methods, established in the 1980s, support millions of transfusions yearly.
• Standard storage involves hypothermic conditions for up to 42 days or sub-zero temperatures for long-term preservation.
• Limitations in these established techniques necessitate refinement and exploration of novel approaches.

Purpose of the Study:

• To review the current state of red blood cell (RBC) preservation.
• To identify opportunities for improving both short-term and long-term RBC storage strategies.
• To discuss recent research addressing limitations in conventional blood banking methods.

Main Methods:

• Literature review of current RBC preservation techniques.
• Analysis of recent research on modifying conventional storage strategies.
• Exploration of alternative approaches to RBC storage.

Main Results:

• Conventional RBC storage methods have remained largely unchanged since the 1980s.
• Recent research has identified ways to address previously unrecognized limitations in RBC storage.
• Studies are exploring both modifications to existing methods and entirely new preservation strategies.

Conclusions:

• There is a significant opportunity to refine RBC storage techniques for improved efficacy and safety.
• Advancements in understanding cellular limitations can lead to better short- and long-term preservation strategies.
• Future research holds promise for enhancing the global blood transfusion infrastructure through improved RBC storage.
